1300F 800 MWe USC CFB BOILER DESIGN STUDY
Concern about air emissions and the effect on global warming is one of the key factors for developing and implementing new advanced energy production solutions today. One state-of-the-art solution is circulating fluidized bed (CFB) combustion technology combined with a high efficiency once-through steam cycle. Due to this extremely high efficiency, the proven CFB technology offers a good solution for CO2 reduction. Its excellent fuel flexibility further reduces CO2 emissions by co-firing coal with biomass. Development work is under way to offer CFB technology up to 800MWe capacities with ultra-supercritical (USC) steam parameters. In 2009 a 460MWe once-through supercritical (OTSC) CFB boiler designed and constructed by Foster Wheeler will start up. However, scaling up the technology further to 600-800MWe with net efficiency of 45-50％ is needed to meet the future requirements of utility operators. To support the move to these larger sizes, an 800MWe CFB boiler conceptual design study was conducted and is reported on herein. The use of USC conditions (～1100℉ steam) was studied and then the changes, that would enable the unit to generate 1300℉ steam, were identified. The study has shown that by using INTREXTM heat exchangers in a unique internal-external solids circulation arrangement, Foster Wheeler’s CFB boiler configuration can easily accommodate 1300℉ steam and will not require a major increase in heat transfer surface areas.
